Joshua Bo Dennis

The Dallas County Medical Examiner determined Dennis died from being stabbed. Garland Forensics Investigators retrieved DNA from blood found at the scene that did not belong to Dennis. The DNA was sent to a laboratory to be analyzed.

On June 4, 2019, detectives received notice from the FBI’s DNA database known as CODIS (Combined DNA Index System) identifying the DNA of Jimmy So being found at the scene of the murder.

After further investigation a murder warrant was obtained and So was arrested on June 5.
